Long Position
A long position means you own an asset — or a contract that behaves like owning it — because you expect its price to rise.
“Going long” is the most familiar trade there is: you buy something and hope to sell it later for more. Traders use the word long so they can describe positions precisely — especially next to its opposite, the short position. Understanding a long position properly means knowing not only how it makes money, but exactly how much you can lose and what changes when you borrow to buy.

A long position in plain words
If you buy one share of a company for $100, you are long one share. If the price rises to $130 and you sell, you made $30. If it drops to $70 and you sell, you lost $30.
That is all a long position is: you benefit when the price goes up. Traders say they are “long” an asset, “long the market” or “long 10 shares”, and the word simply means they own it, or hold something that gains, when prices rise.1
Because a price cannot fall below zero, the worst case for an ordinary long position is losing the money you put in. That is a key difference from short selling, where losses have no ceiling.
How a long position works, step by step
This is the life of a simple long trade in shares paid for with your own money.
You form a reason to expect a rise
It might be a business that you believe is undervalued, an improving trend on the price chart, or a plan to hold a broad index for many years. The reason decides how long you intend to stay in the trade.
You decide how much to risk
Before buying, decide how much of your account the position will use and at what price you will admit you were wrong. This is called position sizing, and it matters more than the entry price.
You place a buy order
A market order buys immediately at the best available price. A limit order buys only at your chosen price or better, but may not be filled at all.
You hold the asset
You now own the shares. Their market value changes every time the price changes. If the company pays a dividend while you hold them, you receive it.
You manage the position
Many traders set a stop loss below the entry to limit the loss, and a take profit level above it to lock in gains. Long-term investors may instead review the position periodically.
You sell to close
The position ends when you sell the same quantity you bought. Until then, any gain or loss is unrealised — it exists on paper only.
You calculate the result
Gross profit = (sale price − purchase price) × quantity. Net profit subtracts commissions, spreads, interest if you borrowed, and taxes, and adds any dividends you received.
Worked examples
Example 1 — The price rises
ProfitYou buy 10 shares at $100 and later sell them at $130.
- A commission of $1 per trade (one to buy, one to sell).
- No dividends; taxes ignored.
| Buy 10 shares at $100 | −$1,000.00 |
| Sell 10 shares at $130 | +$1,300.00 |
| Gross profit ($30 × 10 shares) | +$300.00 |
| Commissions (2 × $1) | −$2.00 |
| Net profit | +$298.00 |
| Return on the $1,000 invested | +29.8% |
The share price rose 30%. After commissions, your return on the money invested is 29.8%.
Example 2 — The price falls
LossSame purchase, but the price falls to $70 and you sell to limit further losses.
- The same $1 commission per trade.
| Buy 10 shares at $100 | −$1,000.00 |
| Sell 10 shares at $70 | +$700.00 |
| Gross loss | −$300.00 |
| Commissions | −$2.00 |
| Net loss | −$302.00 |
Even in the worst case — the company going bankrupt and the shares becoming worthless — you could not lose more than the $1,000 you paid plus commissions. That limit disappears once you borrow money to buy.
Example 3 — The same trade with 2× leverage
LeverageYou have $1,000, borrow another $1,000 from your broker on margin, and buy 20 shares at $100. (In the US, Regulation T lets you borrow up to 50% of the purchase price of eligible stocks.2) Then the price moves 10% either way.
- Margin interest of 8% per year on the $1,000 loan, for 30 days: $1,000 × 8% × 30 ÷ 365 = $6.58.
- No commissions, to keep the arithmetic clear.
| Price rises to $110 — position worth | $2,200.00 |
| Repay the loan | −$1,000.00 |
| Your equity before interest | $1,200.00 |
| Return on your $1,000 after $6.58 interest | +19.3% |
| Price falls to $90 — position worth | $1,800.00 |
| Repay the loan | −$1,000.00 |
| Your equity before interest | $800.00 |
| Return on your $1,000 after $6.58 interest | −20.7% |
A 10% price move became roughly a 20% change in your own money, in both directions, and interest is charged either way. Borrowing doubles the stakes; it does not improve the odds. With higher leverage, a smaller fall can wipe out your equity and lead to liquidation.
Profit and loss of a long position when you close it

Enter a purchase price, a sale price and your costs to see the gross and net result. The calculation runs in your browser.
| Gross result: (sell − buy) × shares | +$300.00 |
| Commissions (open + close) | −$2.00 |
| Net result | +$298.00 |
That is +29.8% of the amount invested ($1,000.00). Break-even after costs: $100.20 — sell above this to make a profit.
Simplified: ignores taxes, spreads, slippage and dividends.

Why traders and investors go long
To participate in growth
Investors who expect a business, or the economy as a whole, to grow over time buy and hold shares to take part in that growth. It is a view about the future, not a guarantee: prices can fall sharply and stay low for years.
To trade an expected move
Short-term traders go long when they expect a rise over days or weeks — after a breakout from a range, for example, or a bounce from support.
To earn income
Owning shares that pay dividends, or bonds that pay interest, produces cash flow in addition to any change in price.
To hedge a short or a future purchase
A business that needs to buy fuel in six months might go long fuel futures today to lock in the price. A trader with a short position might hold a related long to limit risk.
Going deeper
Read as far as you need. Each level builds on the one before it.
Ownership and the limited downside
Beginner
When you buy shares with your own money, you own them outright. Nobody can force you to sell, and the most you can lose is what you paid. This makes a cash long position the safest way to start learning how markets behave.
Break-even, total return and margin
Intermediate
Your break-even price is the purchase price plus all costs per share. With a $100 purchase and $2 in total commissions on 10 shares, you need the price above $100.20 to make any money at all.
Total return includes dividends: buying at $100, selling at $105 and collecting $2 in dividends per share is a 7% gross return, not 5%.
Buying on margin lets you hold a larger position than your cash allows. Losses then come out of your equity faster. Under FINRA rules your equity must generally stay at or above 25% of the market value of the securities, and brokers can require more; if it falls below that level you receive a margin call.3
Long exposure without owning the asset
Advanced
You can be long without holding the asset itself. Buying futures contracts, buying call options, or holding a long perpetual futures contract in crypto all gain when the underlying price rises. Each has a different risk profile: a bought call option can lose at most its premium,4 while a futures position is settled against your account every trading day and you must meet margin calls when it moves against you, so losses are not limited to the margin you first posted.5
Professionals also speak about being long a factor or exposure — for example “long the US dollar” or “long volatility” — meaning their portfolio gains when that factor rises, even if no single position is labelled long.
Advantages and disadvantages
Advantages
- Simple to understand and available in every ordinary brokerage account.
- Without leverage, the maximum loss is limited to the amount you invested.
- Upside is not capped, and you can receive dividends while you hold.
- No borrowing costs when you pay in full, so time is not working against you.
Disadvantages
- Prices can fall for long periods; a long position may stay at a loss for years.
- Your money is tied up, so it cannot be used elsewhere (the opportunity cost).
- Buying on margin magnifies losses and adds interest costs, and can lead to forced selling.3
- Gains are not real until you sell; an unrealised profit can disappear.
Common mistakes
Buying without an exit plan
Deciding when to sell only after the price has fallen leads to hesitation. Decide in advance what would prove the idea wrong, and where you would take profits.
Averaging down without a reason
Buying more simply because the price fell lowers your average cost, but it also increases the size of a losing position. Only add if your original reasons still hold and the total risk remains acceptable.
Confusing a paper gain with profit
An unrealised gain can vanish. If your plan says to sell at a level, follow the plan instead of hoping for more.
Using leverage before understanding it
Margin turns a 10% fall into a 20% or larger loss of your own money, and adds interest. Learn how leverage and liquidation work before borrowing to buy.
Forgetting costs
Commissions, the bid-ask spread and taxes all reduce returns, and they matter more the more often you trade.

Key points to remember
- Being long means you gain when the price rises and lose when it falls.
- Gross profit = (sale price − purchase price) × quantity; net profit also accounts for costs, dividends and interest.
- Without borrowing, the maximum loss is the amount invested; the upside is not capped.
- Leverage multiplies gains and losses equally and adds interest — it changes the risk, not the odds.
- The opposite position is a short position, whose risks are not a perfect mirror image.
